A wonderful write up you got there , great use of words. There are two constant thing in life which I would use to justify what you got up there - Whatever goes up must come down and the other one is - Whatever has a beginning must have an end. So no matter how swift and strong we can be, there's always an end to our life on earth because life itself is a circle with a beginning and an end. I hope you win.....goodluck
